If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.

Tapping sound on startup. Noise gradually goes away in 30 to 45 seconds of driving. Timing chain tensioner was replaced at 34212 miles. Repairs seemed to fix problem. Then after 500 miles tapping sound has come back. Problem not fixed, in fact as I type this my Azera is sitting in dealership garage. Dealership now says they will not fix it clamming the sound is normal. Can you believe that?

Dealer fixed it under warranty. No charge, except for the oil refill, even though the oil interval had not reached the time to change it.
